Questions & Answers / Clarifications

This document provides responses to vendor questions regarding Solicitation # 140R6026Q0037 – ECAO Chiller Compressor Replacement.

• Amperage (MOCP): The existing electrical service is a 100A, 3-pole breaker with a local 100A disconnect. Vendors should submit products closest to the "nominal 50-ton rating" that do not exceed the 100A requirement for maximum steady-state operation.
• Permits: Building modification permits are not required due to federal property jurisdiction. However, the installation must comply with current Larimer County, Colorado electrical code requirements. All installed equipment will be inspected by Reclamation engineers and journeyman level crafts.
• Noise Level (dB): The requirement is no more than 70 dBA. This is achievable under specific conditions: 1) the manufacturer's specification sheet must state the chiller package is rated at no more than 70 dBA, and 2) no more than 70 dBA should be present inside the mechanical room with the entry door shut and the main air handler off, measured 5-feet above the floor adjacent to the door. Refer to AHRI Standard 1280-2014 (R2022) for sound measurement techniques.

These clarifications provide specific details on electrical service limitations, permit requirements, and noise level measurement conditions, which may affect product selection and proposal preparation.
